I read the article, I watched the demo video from the website. Still not convinced he really knows what he's talking about. I for one don't want my touch-based interface married to a kb/m based interface to create some hybrid interface. I want a sleek kb/m ui that doesn't distract, and I want my touch-based device ui's to present content to me quickly, naturally, and contextually. The more buttons/tabs/windows/widgets I have to touch to get to my content, the worse I feel the UI is. I'm for simplicity with underlying complexity, not complexity with underlying simplicity.
